Making a complaint about party political material

Claims in non-broadcast advertisements whose principal function is to influence voters in a local, national or international election or referendum are exempt from the CAP Code. Broadcast political advertising is prohibited in the UK. Ofcom is responsible for considering whether TV or radio ads have been directed towards a political end or placed by an individual or organisation whose aims are of a political nature. Complaints about political bias in broadcast ads should be made to Ofcom.

Please do not submit a complaint to us about political material, as we won’t be able to take any action under the Advertising Codes.
